COMPOSITE SHEET.

' Application led November 11, 1915. `Serial No. 60,921.

To all whom it may concern:

Be itknown that I, EDWARD H. ANGIER, a

l v citizen of the United States, and a resident v of Framingham,

vented an Improvement Sheets, ofv which'the following description, in connection with the accompanying drawings, is a specification', like characters on the drawings representing like parts.

This invention relates to composite sheets and among other objects aims to provide a cheap, soft, absorbent pad for use in connection with surgical operations.

The character of the invention may be best understood by reference to the following description of an illustrative embodiment thereof shown in the accompanying means is typified material which may have its upper .orms a waterproof rece drawing, wherein,-

Figure l is a plan view of the illustrative pad shown herein as embodying the invention with a part broken away;

Fig. 2 is a transverse section 2--2 of Fig. 1; and

Fig. 3 on an enlarged scale is a sectional detail to be referred to.

Referring to the drawing, the illustrative pad shown therein as embod ing the invention comprises a backing l o paper or otfher ace coated with a layer 3 of asphaltum or other suitable waterproof material. To protect this llayer and present a smooth surface, a thin paper layer 5 may be superposed thereon.

Mar 'ns 7 may be bent upward and inward rom the body of the composite sheet `rformed as described, and have their ends at thel corn'ers of the pad overlapped and secured together by an adhesive.

The backing with its upturned margins tacle which may receive any liquid or liquid-containing matter which may be deposited thereon and prevent the escape thereof past the edges of the pad. The margins may be bent upward mor or less according to the capacity desire taken on line An important feature of the invention relates te the provision of absorbent means which may be superposed upon the backing or container described. r[his absorbent herein in the form of a woven layer made up of paper strands 9 extending in one direction, and similar Strands 11 extending transversely thereto.

Massachusetts, have in-v in Composite Each strand may be made of a large sheet of tissue paper which may be crumpled or compacted by drawing the same throu h a funnel. For example, a sheet' of thin tissue paper thirty-sixI inches in width may be drawn through the funnel and compacted to form a strand three inches in width. When thus compacted, the strand will present considerable fullness and have an extended surface capable of absorbing a large Specification of Letters Patent. Patented Sept. 14, 1920@ l les amount of liquid and having a desirable cushion effect.

Obviously, the strands maybe assembled with a varying closeness or tightness according to conditions of use. Substantial intersticesmay occur at the juncture of the crossing strands and present depressions into which `liquids deposited on the 1 pad will quickly gravitate owing to the fact thatthe surfacing of the paper usually has a sizing or finish which would oi'er a slight resistance to the absorption of the liquid thereby. This resistance, however, is quickly overcome and the water enters the p aper if it is allowed to rest thereon. The water on gravitating from the high Spots of the crossing strands into the depressions between them., may spread and How beneath said strands, along the smooth surface of the backing and thereby be distributed to a substantial part of the pad and prevent over-saturation thereof locally. i

ln drawin or compacting the large sheets into relative y small strands as' described, suiiicient air may be''p0cketed within 'the strands which will contribute rto their fullness and add to the cushion effect' thereof.

The absorbent la ervmay have its edges inserted beneath an secured to the backing margins as by an adhesive. In some cases the absorbent la er may be secured to 'the backing by an a hesive and the longitudinal and transverse strands may have their'crossing` points in adhesive en agement.

o contribute to the esirability of the ad for surgical purposes,-the paper torming lthe absorbent cushion strands may be treated with any suitable sterilizing agent. 'A sheet 13 of gauze or netting maybe spread over the upper surface of the absorbent layer and have its margins secured to the Aedges of the backing. This sheet willserve strands of the absorbent sheet have been shown as Woven, they may be otherwise arranged. l41 or example, they may simply cross Without being Woven or they may be stretched across the backing parallel to one another. bviously any number of layers of the absorbent material mayl be provided to produce more or less absorbent the cushion e'ect as desired.

The pad described may be of any area Yor made upinto any form desired. One i1nportant use would be as a substitute for the cotton sheets now placed on the operating table beneath patients. F rom the above description the advantages of the pad in this use will be obvious. t serves as a soft, clean cushion for the patient to rest on and its high absorbent quality will materially add to the comfortof the patient. The pad is so cheap that after once used it may be rolled or folded up, removed and destroyed.

1While' the pad has been described more particularly as adapted for use in connection with surgical operations, it will be understood that its field of use is not restricted thereto.

. Having described one illustrative ernbodi ment of the invention Without limiting the maar@ "uses,4 comprisingl a tray having upturned edges and formed of paper having a Waterproof coatlng and an absorbent fabric 1n said tray Woven with strands formed fromcrumpled sheets of absorbent paper.

3. An absorbent pad for surgical and like uses, comprising a liquid receiving tray having inturned edges and formed of paper having a Waterproof coating and an absorbent foraminous body in said tray conned by.

said edges.
